ABSTRACT OF THE DISCLOSURE An improved vehicle suspension system for use on axles of trailers, trucks, and the like. A pair of wheels are individually rotatably mounted on stub axles attached to a pair of trailing arms which are connected to and extend radially rearwardly from a pair of pivot sleeves. The sleeves are pivotally mounted on brackets connected to the vehicle frame. A pair of spaced levers are attached to and extend radially outwardly from each of the pivot sleeves and rotate in unison with the trailing arms An annular elastomer spring is located between a pair of metal end plates which are pivotally mounted on and located between the spaced levers. One of the end plates is connected to the lever by a hollow shaft and another shaft is connected to the other end plate and extends through the elastomer spring and into the hollow shaft to maintain the spring in axial alignment. The elastomer spring, in combination with the dual trailing arm and associated lever mounting arrangement, provides a balanced force on the vehicle tires and trailing arms during vehicle braking and upon the tires encountering road obstructions as well as during static conditions.
